Abstract

A reactor vessel and an associated process for preparing a controlled-dosage chlorine dioxide solution. The vessel (1) according to the invention comprises a hollow body (2) inside which there are provided two chambers (3, 4) which have different volumes; each chamber has, in an upper region, an opening which is closed by a removable closure (7, 8) and the chambers are mutually connected by a substantially horizontal duct (5) with openings (5a, 5b) arranged in a region which is spaced upward with respect to the bottom (2) of the two chambers. The vessel (1) according to the invention is particularly suitable for preparing a disinfectant and highly pure chlorine dioxide solution, minimizing the risk of developing noxious gases.
